The world as we know it has come to an end, the Arctic shelves slipped away into the sea and the Ice Caps at the Antarctic had began to melt, capital cities all over the world have been flooded and humanity is fighting for control. Take your place in a post-apocalyptic world, establish a new civilization with your rules, and forge alliances with friends to expand your civilization and fight to retain control in Reborn Horizon.

Reborn Horizon has a great questing system that can be divided into three sections, City, Military, and Economy. Each quest line offers players a large variety of different quests, and each will provide rewards related to that particular section. This gives players the option of choosing to specialize in a certain area, or branch out and embrace all three reward types. Rewards get greater depending on the level of quest you're doing so both techniques work, allowing for multiple ways of advancing in the game.

As with every free online RPG game in today's market, Reborn Horizon offers players intensively strategic PvP that sets it apart from competitors. Before launching your troops into battle you must train them, and ensure you have enough workers in your army to carry the required amount of food, then you may choose the enemy that you wish to pillage. Players have the option of scouting an enemy stronghold before attacking, providing highly relevant tactical information such as the total number of soldiers in garrison or the amount of resources available to steal. With enough troops you will defeat your enemies and loot their resources. Another great aspect to the PvP in Reborn Horizon is the Valley system. There are a number of special Valleys around the map and players that manage to remain in control of one these Valleys get an income boost for certain resources, making them highly contested, PvP hot spots.
